Getting “At least one JPA metamodel must be present” with @WebMvcTest

Question

I\'m fairly new to Spring, trying to do some basic integration tests for a @Controller.

@RunWith(SpringRunner.class)
@WebMvcTest(DemoController.clas         


        

Answer 1

Remove any @EnableJpaRepositories or @EntityScan from your SpringBootApplication class instead do this:

package com.tdk;

@SpringBootApplication
@Import({ApplicationConfig.class })
public class TdkApplication {

    public static void main(String[] args) {
        SpringApplication.run(TdkApplication.class, args);
    }
}

And put it in a separate config class:

package com.tdk.config;

@Configuration
@EnableJpaRepositories(basePackages = "com.tdk.repositories")
@EntityScan(basePackages = "com.tdk.domain")
@EnableTransactionManagement
public class ApplicationConfig {

}

And here the tests:

@RunWith(SpringRunner.class)
@WebAppConfiguration
@WebMvcTest
public class MockMvcTests {

}
